A few years ago, downtime of the server wouldn't have been an issue.
These days the server is used for all phones, TV, Internet connection,
Lighting control (CBus). We're in the bush without a decent computer
store nearby so a failed PSU is likely 1-2 days downtime. Hot-plug disks
is mainly a convenience. Not only from replacement of failed disks but
also upgrading of each disk in the array with larger disks sometime in
the future which would be a pain without hot-plug disks.

I hadn't realised the functionality of these filesystems extended to
raid. I'll have to investigate these further. However the lack of raid 5
or 6 would probably rule out BTRFS for me.
